This has been a test of the emergency broadcast system. Had this been an actual emergency, the tone you have just heard would have been followed by information and instructions.
Ironically, had the emergency been severe enough, it is entirely possible that we would not have been able to generate the tone and issue instructions in the first place. Which in fact means that the severest and most dire of emergencies are, for all intents and purposes concerning the emergency broadcast system, utterly indistinguishable from a state of no emergency at all.
It is worth considering, therefore, that at any moment of apparent normalcy, an emergency of the gravest and most imminently deadly proportions is unfolding that cripples the very infrastructure of your local crisis-management system. Taken in this light, the sounding of the tone over your radio or television system should be regarded as a sign that, whatever is happening, the means to deal with it are still fully in place and operational. We therefore suggest that the sound of the tone be a source of comfort, rather than alarm.
We repeat, the sound of the tone is a source of comfort, rather than alarm. The sound of the tone means that everything is being dealt with. The sound of the tone means that you need only stay at home, and listen to the instructions on your radio or television set. As long as you hear the tone and follow the instructions, everything will be okay. The only time when things may not be okay is when you cannot hear the tone and follow the instructions, so it is therefore advisable that you leave your radio or television set on at all times. Because, in the end, there really is no better guarantee of your personal safety than hearing the tone and following the instructions.
This concludes our test of the emergency broadcast system. We now return to our regularly scheduled programming, already in progress.
